Title: Rewritable read only memory
Inventor: TAKEBUCHI MASATAKA
IPC: H01L21/8247
Filed: 1987-08-27
Abstract: PURPOSE:To prevent decrease in charge keeping ability due to miniaturization of a memory cell and deterioration of an oxide film due to capture of holes and to enhance carrier injection efficiency, by forming a three-layer structure of a gate insulating film, in which an oxide film, a nitride film and an oxide film are overlapped sequentially from the side of a semiconductor substrate. CONSTITUTION:A field region 22 is formed on a P-type silicon substrate 21. Then, an oxide film is formed on the substrate 21 in dry oxygen. Channel implantations are performed twice through the film under the different conditions. Then, said oxide film is removed. An oxide film 23 is formed again in dry oxygen. A nitride film 24 is formed on the film 23. Then, an oxide film 25 is formed by a hydrogen burning oxidation method. A polysilicon film 26 is formed on the film 25. Phosphorus is diffused from the upper part of the film 26. Then, the phosphorus is oxidized in a dry atmosphere, and an oxide film 27 is formed. After a polysilicon film 28 is deposted, phosphorus is diffused. Etching is performed by a photolithography technology so that only a gate region is made to remain as it is. Source and drain regions 29 are formed by ion implantations in a self-aligning mode.

Title: Surface acoustic wave element
Inventor: IEGI EIJI
IPC: H03H9/145
Filed: 1987-08-27
Abstract: PURPOSE:To improve the reliability and to simplify the manufacture process by forming plural bumps to a specific location on a piezoelectric substrate or a piezoelectric film and laminating a lead electrode at least a part of the surface of each bump. CONSTITUTION:Plural inter-digital electrodes 5 and a lead electrode 3a to extract the inter-digital electrodes 5 externally are formed onto a piezoelectric substrate 1 or a piezoelectric film to form a surface acoustic wave element. Then plural bumps 2 are formed to the specific location on the piezoelectric substrate 1 or the piezoelectric film and the lead electrode 3 is laminated to at least part on the surface of each bump 2. Since the bumps 2 are formed directly onto the upper part of the piezoelectric substrate 1 or the piezoelectric film in this way, the treating process is formed by a simple mask vapor- deposition method and the manufacture cost can be reduced. Since the bumps 2 are formed before the inter-digital electrode 5 and the lead electrode 3 are formed, a problem of damage caused to the electrodes due to contact with the vapor-deposition mask does not exist.

Filed: 1989-08-19
Abstract: PURPOSE:To keep gas reaction constant or decrease the changing ratio of the gas reaction by housing an exciting means which balances a free piston against the total pressure of gas and thermal sensing liquid in a space part in a second chamber divided by the free piston opposite to a third chamber. CONSTITUTION:A thermal sensing liquid 9 expands to displace a free piston 14 so as to withdraw from a third chamber 13 through a rod 18 when a tempera ture therearound is increased. The, a space part 12a is widened to increase volume occupied by a gas 2, while gas reaction is kept constant or the ratio of the gas reaction change is decreased. The free piston 14, on the other hand, is moved to the side of the third chamber 13 so as to decrease the volume occupied by the gas 2. The pressure of the gas 2 is not reduced irrespective of the decrease of the temperature, and the gas reaction is kept constant or the gas reaction change is decreased. The gas reaction is thus adjusted by utilizing a single diameter cylinder 10 according to a temperature change.

Title: Measuring apparatus for stress
Inventor: NISHIMOTO SHIGETO
IPC: G01L1/00
Filed: 1990-08-13
Abstract: PURPOSE:To lengthen a service life of a battery to reduce interruption of measurement and reduce man-hours and a cost accompanied with replacement of batteries by amplitude-modulating carriers by a differential signal which exceeds a constant value among detection signals. CONSTITUTION:A bridge circuit comprising four strain gauges detects a strain corresponding to a stress applied to a cross pin part and outputs a detection signal S1. The detection signal S1 is amplified in an amplifier circuit 2 on the next stage and rectified by a full wave rectifying circuit 3 to be output as a voltage signal S2 to a subtraction circuit 4. Then a constant voltage value A is subtracted from the voltage signal S2 in the subtraction circuit 4, and a carrier from a carrier generator 6 is amplitude-modulated by a signal S3 which is the result of the subtraction in modulator 5. The modulated signal is amplified in an amplifying circuit 7 and then sent out from an antenna 8 toward a receiver as a radio signal. Since the carrier is thus amplitude- modulated by a differential signal which exceeds a constant value among detection signals, a small amount of power is required for modulation and amplification of an order number, so that consumption of a power battery is suppressed and a useful life can be lengthened.

Title: Voltage controller for vehicle generator
Inventor: MARUYAMA TOSHINORI
IPC: H02J7/16
Filed: 1991-07-31
Abstract: PURPOSE:To prevent fluctuation of engine rotation by preventing abrupt increase of field coil exciting duty at the time of abrupt increase of electric load. CONSTITUTION:A generated voltage VB is compared with a reference voltage Vr through a comparator 11 output therefrom is then compared with a sawtooth wave to produce a duty pulse comparing signal S1 having a predetermined period, and the exciting duty of a field coil 21 is controlled by a gate pulse signal S2 through a transistor 12. When the gate pulse has '1' level, an up- counter 13 functions and the count thereof is stored, as a value representing the exciting duty, in a latch 14. A pulse width generating circuit 15 then generates a pulse having pulse width corresponding to thus stored count plus 1 and thus generated pulse is fed to a gate 102. When an electric load 2 increases abruptly to sustain '1' level of the comparison signal, the gate opens and gate pluse signals increasing sequentially count by count are fed to the transistor thus increasing the exciting duty gradually.
